Guhring 9031500087300 Square End Mill 0.3438 in 4 Flute

Product Description

The GUHRING 9031500087300 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous metals in machine shop and manufacturing environments. Built to Series 3150 standards, it features a 0.3438-inch cutting diameter, a 1-inch length of cut, and a 0.375-inch straight cylindrical shank. The 4-flute, right-hand spiral geometry with a 30-degree helix angle provides efficient chip evacuation and smooth cutting action. The bright, uncoated finish is standard for general-purpose applications. Machinists and CNC operators rely on this tool for slotting, profiling, and peripheral milling in ferrous and high-strength materials.

This end mill is suited for milling cast iron, stainless steel, and steel across a range of machining centers and manual mills. The centercutting capability allows direct plunge entry into the workpiece, supporting versatile operation on CNC machining centers and knee mills. At 2.5 inches overall length with a regular-length flute configuration, it fits standard toolholding in most production and job-shop setups. The straight cylindrical shank with h6 tolerance ensures a consistent, repeatable fit in collet chucks and end mill holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous applications
• 4-flute right-hand spiral with 30-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge milling
• Bright uncoated finish suited for general-purpose dry or light-coolant machining
• Shank diameter tolerance h6 and mill diameter tolerance h10 for precise toolholder fitment
• No chipbreaker geometry for clean finish cuts on smooth surfaces

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard collet chucks and end mill holders accepting a 0.375-inch straight cylindrical shank. Primary workpiece materials are cast iron, stainless steel, and steel; secondary materials include non-ferrous and superalloy classifications per material codes N and S.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after clamping to protect both the tool and the workpiece surface finish.
